PIPEBCOUPLING.

SPECIFICATION forming part of Letters Patent No. 284,096, dated August 28, 1883,

Application filed December l2, 188:2. (No model.)

.To @ZZ whom t may concern,.-

Be it known that I, J oHN WALTER, a citizen of the United States, residing at Nashville, Davidson county, and State of rllennessee, have invented a new and useful Pipe-Goupling, of' which the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and letters of reference marked thereon, in which- Figure l is a representation of the ends of two lengths of' pipe A A, held together by the coupling-ring G and the key B. Fig. 2 is a representation of' the coupling-ring G separated from the pipe ends A A. Fig. 8 represents the key B separated from the couplingring G. Fig. 4 represents asection of the key B transversely through the center of the key, aud Fig. 5 represents a section of the pipe A A and coupling-ring G, showing at H raised corrugations and at l sunken corrugations in the pipe A A.

Similar letters referto similar parts throughout the several views.

The pi pe-coupling may be applied to smokepipes, heat-pipes, or other pipes where a cheap and strong coupling is desired. y My invention relates to improvements in pipe-couplingsin which the sections are united withoutinterlocking them together or riveting them; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth, and pointed out in the claims.

Referring to the drawings, A A represent sections of' a pipe, each provided with end flanges, K K, which abut against each other. Each section is also provided with a raised or sunken corrugation, H I, near its ends, for a purpose hereinafter explained.

Gr represents the coupling-ring, provided with the central outwardly-projecting corrugation, C, and the similarly-formed corrugation is made of sheet or cast metal, with side flanges turned downwardly and inwardly, so as to fit over the fianges E of the coupling-ring and clasp the ring G in place at the junction of tw'o sections of' the pipe. The upper end of the key B is turned up to form a handle, 71 to operate the key B.

In practice the sections to be united are placed so that the flanges K abut against each other, the coupling-ring is clasped around the sections so that the corrugations in the ring engage with the corrugations in the sections and the flanges on the ends of the sections, and the key is applied to fasten the ends of' the ring to the sections.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination, with the sections of a pipe having corrugations near the ends of its sections, of the open corrugated coupling-ring having end iianges, and a key fitted to slide over said ilanges, substantially as shown and described.

2. The combination, with the sections'A A of a pipe, having corrugations H H and flanges K K, of.the coupling-ring G, provided with the corrugations C D and end fianges, E, and key B, fitted to slide over said 'iianges, substantially as described, and for the purpose set forth.

Jer-1N WALTER.
